8 Gains.' (Cl. 141-4) b This invention relates to so-called cleaning machines of a character suitable for washing or otherwise treating metal parts, machines and priate baths or solutions.

The primary object ofthe invention is an improved cleaning machine of this character which is of simple and trouble-free constructions and so organized as to facilitate the handling of the In the accompanying drawing, Fig. l isa' side elevation, partly broken out, illustrating a preferred form of tlieiinvention; Fig. 2 is a plan approthe entire open top of the basket is free oflgany obstruction by or from its supporting means.

Means is provided for oscillating the rock shafts in synchronism to. impart a. vertical, re-

, ciprocatory motion to the work suspended from A one of them and cross-connecting'such shaft to view; and Fig'. 3 is a side elevation illustrating a modifledfor'm of actuating mechanism.

The preferred form of machine illustrated'is portable, and comprises a rectangular tank generally designated-I mounted on casters 2. Ex-

tending transversely across the ends of the tank i on each rock shaft. Each arm is provided with Y an upwardly opening recess I from which the work to be treated can be suspended, either directy or as below described, and in such fashion as to be readily inserted into and removed from die tank.

For many uses it is convenient to suspend the v work within the-tank in a foraminated carrier,

or a basket as it is herein termed, such as the mesh-bottoni basket 8 shown in the drawings.

adapted for engagement with the work supportrails i' secured to the load eiects the downward movement of the arms the other, so that the shafts oscillate in synchronism but in opposite, rotary directions.

In -the preferred arrangement illustrated in Figs. 1 and 2, sprocket wheels II and I2 are secured to the projecting ends of rockshafts 3 and 4, respectively, anda drive chain I3 is oppositely or reversely trained on the two wheels, i. e. over wheel II and under"E wheel I2. The otherwise free end of that portion of the chain which engages wheel I2 is secured to that wheel, as at I4; and means is provided for alternately drawing upon and releasing the other end of the chain to an extent appropirate to the stroke required of the work supporting arms 6. As will' be understood, |the weight of the basket and its -as permitted by the release of the chain. In other words, the arrangement is such that theupward movement of the basket is effected by I5 protruding from a disc I6 secured to a shaft I`|.' The latter is arranged to be dn'ven by a motor I8 through suitable reduction gearing gen- Such basket; otherwise of any suitable construc- Y tion, is provided adjacent its ends with bails ing arms B. As shown, the hails comprise pairs f of upwardly extending arms l pivotally attached to the side walls of the basket and united at rtheir upper ends by cross bars I0 adaptedto seat in the recesses 1 of the work supporting As y will be apparent, the basket is thus readily removable; also, if it is desired to load the work into the basket when the.v latter, is in position in erally designed I9., Y

In the construction illustrated in Fig. 3, crank, arms 20 and 2l are mounted on the ends of rock shafts 22 and 23, respectively, and arms 20 and 2| are cross-coupled by a rigid connecting rod 24. An extension 'of crankuarm 20 provides a driving crank arm 254 which'is actuated by rod 26, crank pin 21, disc 28 and shaft 29. As above, shaft 29 is driven by.a motor I8 through reduction gearing I9. All other parts of the apparatus are as 'already described and are correspondingly numbered.

In the light of the foregoingv description the following is claimed:

l. In a washing machine the combination with a tank. of a basket therein, hanger members up- I downward movement by otally connected thereto, a cross bar extending transversely above each end of the basket and each uniting a pair of hanger members, two transverse, horizontally disposed rock shafts journaled inthe side walls of the tank beyond the ends'of the basket, -a pairof inwardly pro- 'iecting supporting arms mounted on each rock lshaft and having upwardly opening recesses to standing from the corners of the basket and pivotally connected thereto, a cross bar extending transversely above each end-of the basket and each a pair of hanger members, two

transverse, horizontally disposed rock shafts journaled for support beyond the ends of the basket, inwardly projecting supporting arms mounted on each rock shaft and having upwardly opening recesses to receive and removably support said cross bars, and means for oscillating said rock shafts in synchronimn to impart a vertical reciprocatory motion to the basket through said supporting arms.

3. In a washing machine the combination with a tank, or a basket therein, hanger members npstanding from the corners of the basket, a cross bar extending transversely above each end of the basket and each uniting a pair of hanger members, -two transverse, horizontally disposed rock shafts journaled for support beyond the ends of the basket, inwardlyprojecting supporting arms mounted oneach rock shaft and having upwardly opening recesses to receive and removably support said cross bars, and means for oscillating said rock shafts in synchronism to impart a vertical reciprocatory' motion to the basket through said supporting arms,

4. In a washing machine the combination with a tank, of a basket therein, hanger members upstanding from the corners of the basket and pivotally connected thereto, a cross bar extending transversely above each end of the basket and v each uniting a pair of hanger members, two transverse, horizontally disposed rock shafts journaled for support beyond the ends of the basket, inwardly projecting supporting `arms mounted on each rock shaft and adapted toreceive and support'said cross bars, and means for oscillating said rock shafts in synchronism to `impart a vertical reciprocatory motion to the basket through said supporting arms.

5. In a washing machine the combination with a tank, of a basket therein, hanger members upstanding from the corners of the basket and pivotally connected thereto, a cross bar extending transversely above each end of the basket and each uniting a pair of hanger members, two transverse, horizontally disposed rock shafts journaled in the side walls of the tank beyond the ends of the basket, a pair of inwardly projecting supporting arms mounted on each rock shaft and having upwardly opening recesses to receive and removably support said cross bars, a

l sprocket wheel mounted on the end of each rock over-all length less than the distance between the rock shafts, a bail upstanding from adjacent each end of the basket and removably engaged with the said recesses, and means for oscillating said rock shafts in synchronism to impart a vertical reciprocatory motion to the basket through said members and hails.

7. In a washing machine the combination with a tank, of a. basket therein, hanger members upstanding from the corners of the basket, a cross bar extending transversely above each 'end of the basket and each uniting a pair of hanger members, two transverse, horizontally disposed rock shafts journaled for support beyond the ends of the basket, inwardly 'projecting supporting arms mounted on each rock shaft and hav-ing upwardly opening recesses to receive and removably support said cross bars, the free ends of said supporting arms terminating adjacent said recesses and engaging the said cross bars on the outer sides of the hanger members to provide free access to the entire open top of the basket, and means for oscillating said rock shafts in syn- .chronism to impart a vertical reciprocatory motion to the basket through said supporting arms.

8. In a washing machine the combination with a tank,'of a'basket therein, hanger members upstanding from the corners of the basket, a cross bar extending transversely above each end of the basket and each uniting a pair of Vhanger members, two transverse, horizontally disposed rock shafts journaled for support beyond the ends of the basket, inwardly projecting supporting arms mounted on each rock shaft and having upwardly opening recesses to receive and removably support said cross bars, the said supporting arms engaging extended portions of' said cross bars beyond the sides of the basket, and means for oscillating said rock shafts in synchronism to impart a vertical reciprocatory motion to the basket through said supporting arms.
